Flooding rivers have caused many human and financial losses. Hence, performing studies, investigations and subsequent actions are consistent with the nature of the river is necessary and inevitable. But the behavior of rivers has a lot of complexity and in this respect, computer models are efficient tool in order to study and simulate the behavior of rivers with the least possible cost. In this paper, one-dimensional model HEC-RAS was used to simulate the flood zoning in the Kota Tinggi... Topics: Computer modeling, floodplain zoning, MIKE11, HEC-RAS, GIS
The article discusses questions related to the integrated use of mineralogo-geochemical research methods of ore deposits under exploration and mathematical modeling of behavior of ore minerals in the hypergene zone for qualitative and quantitative assessment of potential ecological threat of pollution by toxic elements, that is one aspect of reducing risk of technogenic disasters related to the mining activities of human. Topics: Toxic Pollution, Tailings Dam, Ore Minerals, Computer Modeling
The paper presents the effectiveness of the parametric integral equation system (PIES) in solving 3D boundary problems defined by Navier-Lame equations on the example of the polygonal boundary and in comparison with the boundary element method (BEM). Analysis was performed using the commercial software “BEASY” which bases on the BEM method, whilst in the case of PIES using an authors software. On the basis of two examples the number of data necessary to modeling of the boundary geometry,...

Given for UNC ENVR 400 seminar 12n 17 Mar 2010 (see http://www.unc.edu/~weinberg/400/archive/spring2010/). Ms Shankar is a PhD student in Environmental Sciences and Engineering at UNC Chapel Hill and a research associate in the UNC Institute for the Environment. Ambient air pollutants can damage the health of humans and their environment, including the climate system. To mitigate these harms we must identify the responsible atmospheric constituents, and understand their physical and chemical...
